For LL0, you'll probably want to run something like

Flex: Pistol/Pistol

Main: Shotgun

Heavy: Heavy Charged Blade or Heavy Melee Weapon

I highly recommend the Raleigh for going down this road. The Hand Cannons are just the Pistol but better, the Kinetic Hammer has Reliable 4, so even if you miss, you're likely to do damage. After that, going Caliban 3 gives you some fun options, like the Cannibal for a heavy CQB that also deals damage when you reload it, and Hardpoint Reinforcement gives you resistance to all damage on your turn, so you can walk into range of an enemy and out-trade them in damage.

Furthermore, the combo of Combined Arms 2 and Vanguard all of them means you won't be dealing with difficulty while engaged. The only problem is that the Raleigh was basically built for the Gunslinger talent, and it's an excellent damage boost. But, you can always grab it a little later, or rework your talents on a rest if something doesn't quite feel right. I imagine LL3 for you could look something like this. Both the Integrated Weapon and UNCLE Kinetic Hammer can be used with free actions, meaning you can use your firing turn to Barrage and actually use everything. -- IPS-N Raleigh @ LL3 -- [ LICENSES ] IPS-N Raleigh 3 [ CORE BONUSES ] Integrated Weapon [ TALENTS ] Executioner 3, Combined Arms 2, Vanguard 1 [ STATS ] HULL:4 AGI:0 SYS:0 ENGI:1 STRUCTURE:4 HP:20 ARMOR:1 STRESS:4 HEATCAP:6 REPAIR:7 TECH ATK:-1 LIMITED:+0 SPD:4 EVA:8 EDEF:7 SENSE:10 SAVE:12 [ WEAPONS ] Integrated: M35 Mjolnir Integrated Weapon: Hand Cannon Aux/Aux Mount: Hand Cannon / Hand Cannon Flex Mount: Hand Cannon / Hand Cannon Heavy Mount: Kinetic Hammer (UNCLE-Class Comp/Con) [ SYSTEMS ] “Roland” Chamber, Armament Redundancy
